  Go to Plants of the Week Advanced Search Welwitschia mirabilis  Hook.f. (=  W. bainesii  (Hook.f.) Carr.) Family:  Welwitschiaceae Common names:  welwitschia (Eng.), tumboa, n'tumbo (Angolan), tweeblaarkanniedood (Afr.), !kharos (Nama/Damara), nyanka (Damara), khurub (Nama), onyanga (Herero) Weird, peculiar, wonderful, strange, bizarre, fascinating, and of course, unique, are the kind of words that are used to describe the welwitschia. It is one of the few things on Earth that can truly claim to be one of a kind. There really is nothing like it. Description An adult welwitschia consists of two leaves, a stem base and roots.That is all! Its two permanent leaves are unique in the plant kingdom.They are the original leaves from when the plant was a seedling, and they just continue to grow and are never shed. They are leathery, broad, strap-shaped and they lie on the ground becoming torn to ribbons and tattered with age. The stem is low, woody, hollowed-out, ...

Benefits of plants

  Plants Make Us Happier When you feel down, it’s amazing what a walk in the park can do. That’s because when we get in touch with nature,  we improve our wellbeing . Studies show time spent outside in green spaces can reduce our mental fatigue, increase our relaxation, and even  improve our cognition . Plants Improve Our Environment Now that we know a little bit more about how plants can improve how we feel, let’s talk about how they can improve our environment. Plants can instantly beautify a space, but they can also contribute to improvements we can’t see, like indoor air quality. Indoor plants can improve indoor air quality in a few ways. Through photosynthesis, plants absorb carbon dioxide and release oxygen, while through transpiration and evapotranspiration, plants release moisture vapor and increase humidity. Boost moods, productivity, concentration, and creativity Reduce stress and fatigue Clean indoor air by absorbing toxins, increasing humidity, and producing o...

Importance of plants

Plants play a crucial role in the functioning and sustainability of our planet. They are not only essential for the survival of various ecosystems but also have significant importance for human life. The importance of plants can be observed in several aspects, including environmental, ecological, economic, and social dimensions. Environmental Importance: Plants are primary producers that form the foundation of food chains and webs in ecosystems. Through the process of photosynthesis, plants convert sunlight, water, and carbon dioxide into oxygen and glucose, providing the oxygen necessary for all aerobic organisms to breathe. This oxygen production is vital for maintaining the balance of atmospheric gases and supporting life on Earth. Additionally, plants act as carbon sinks by absorbing carbon dioxide from the atmosphere and storing it as organic matter, helping to mitigate climate change. Furthermore, plants play a crucial role in regulating the water cycle. Through their roots, they...

Types of plants

There are numerous types of plants, each with its own unique characteristics and adaptations. These plants can be broadly categorized into several groups based on different criteria such as their life cycle, habitat, and reproductive strategies. Here are some of the main types of plants: 1.  Angiosperms : Angiosperms, also known as flowering plants, are the most diverse group of plants on Earth. They produce flowers and fruits, which contain seeds. Angiosperms can be further divided into two main categories: monocots and dicots. Monocots have one cotyledon (seed leaf) while dicots have two cotyledons. 2.  Gymnosperms : Gymnosperms are a group of seed-producing plants that do not produce flowers or fruits. Instead, they have naked seeds that are exposed on the surface of specialized structures called cones or strobili. Examples of gymnosperms include conifers (such as pine trees), cycads, ginkgoes, and gnetophytes. 3.  Ferns : Ferns are non-flowering vascular plants that r...

History of plants

The Early History of Plants The history of plants dates back millions of years to a time when the Earth was a vastly different place. The earliest known plants were simple organisms such as algae and mosses, which evolved around 3.5 billion years ago during the Eoarchean era of the Precambrian period. These early plants were single-celled organisms that were able to photosynthesize, producing energy from sunlight and water. Over time, plants evolved to become more complex and diverse, with the development of multicellularity and the appearance of vascular tissues. The first vascular plants, such as the Rhyniopsida and the Prasinophyta, emerged around 300 million years ago during the Devonian period. These plants were characterized by the presence of xylem and phloem tissues, which allowed them to transport water and nutrients throughout their bodies. The Age of the Dinosaurs During the Mesozoic era, which spanned from 252 million to 66 million years ago, plants underwent a period of ra...
